Getting Started
-
If you're brand new to Ruby and Rails, please see Discourse as Your First Rails App or our Discourse Vagrant Developer Guide, which includes instructions to get up and running in a development environment using a virtual machine.
-
If you're familiar with how Rails works and are comfortable setting up your own environment, use our Discourse Advanced Developer Guide.
Before you get started, ensure you have the following minimum versions: Ruby 1.9.3+, PostgreSQL 9.1+, Redis 2.6+. If you're having trouble, please see our TROUBLESHOOTING GUIDE first!
Setting up a Discourse Forum
If you want to set up a Discourse forum for production use, see our Discourse Install Guide.
Vision
Discourse is a Civilized Discourse Construction Kit, a free, flexible, fundamental building block for online discussion communities of any size, tiny to huge.
-
A flattened, endlessly scrolling discussion, avoiding the awkwardness of traditionally threaded and paginated discussion, where replies can be expanded in place for context.
-
A user trust system that grants users rights to assist in governing the forum as they participate in good faith over time. The goal is for the forum to be nearly self-moderating in the absence of any formal moderators, although excellent moderators always accelerate the process greatly.
-
An advanced JavaScript app which runs in modern browsers and works identically on desktop and tablet and smartphone without the need for a native app.
-
A contemporary, robust technology stack, free of legacy PHP and MySQL constraints.
Internet discussion belongs to everyone, not just huge corporate websites. Our goal is to foster an active community of contributors, all of whom commit to free, simple, pleasant to use online discussion software that can thrive in an Internet age dominated by micro-blogging and diminishing attention spans.
Discourse is built for the next 10 years of the Internet, so our requirements are high:
Up-to-date desktop browsers:
- Internet Explorer 9.0 (may not be fully functional), 10.0+
- Firefox 16+
- Google Chrome 23+
- Safari 5+
Latest generation of tablets:
- iPad 2+
- Android 4.1+
- Windows 8
Modern mobile/smartphones:
- iOS 6+
- Android 4.1+
- Windows Phone 8
Built With
Discourse is built from the following open source components:
- Ruby on Rails - Our back end API is a Rails app. It responds to requests RESTfully and responds in JSON.
- Ember.js - Our front end is an Ember.js app that communicates with the Rails API.
- PostgreSQL - Our main data store is in Postgres.
- Redis - We use Redis for our job queue, rate limiting, as a cache and for transient data.
Plus lots of Ruby Gems, a complete list of which is at /master/Gemfile.
